Description

Technical Field

[0001] This utility model relates to the field of track maintenance tools, specifically a turnout dual-purpose hydraulic clamp. Background Technology

[0002] Currently, there are no specialized tools available for removing turnout gauge blocks and turnout eccentric sleeves. Routine operations typically involve using a pry bar to remove these components (see attached document). Figure 1 As shown, the bottom of the crowbar has a clamp. One end of the clamp is pressed against the gauge block, and the other side of the clamp is hinged to engage the rear side of the eccentric sleeve. The crowbar is manually rotated to move it horizontally out of the turnout. The operation is inefficient and poses safety hazards during the operation, which can easily damage the eccentric sleeve.

[0003] This case arose to address the difficulty in removing the turnout gauge block and eccentric sleeve. Summary of the Invention

[0004] Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides a dual-purpose hydraulic clamp for turnouts, which solves the problems mentioned in the background section.

[0005] Technical solution To achieve the above objectives, this utility model is implemented through the following technical solution: a turnout dual-purpose hydraulic clamp for horizontally removing the eccentric sleeve from the turnout gauge block, comprising a thruster and a clamp body component. The clamp body component includes a clamping clamp plate for hooking and positioning the eccentric sleeve onto the gauge block. The clamping clamp plate is hinged to a pushing clamp plate at an adjacent location via an adjusting plate. After the pushing clamp plate is angularly adjusted relative to the adjusting plate, it hooks to the rear side of the eccentric sleeve to achieve positioning and engagement of the eccentric sleeve. The thruster applies horizontal force to the pushing clamp plate.

[0006] Preferably, the thruster and the clamp body are respectively provided with corresponding connecting structures. The connecting structure includes a sleeve seat and a clamp mounted on the upper side of the clamping clamp plate. The sleeve seat is fixed on the upper side of the clamping clamp plate, and a screw is welded to the lower end of the clamp. The screw is threaded to the sleeve seat for fixation.

[0007] Preferably, an extension block is provided on the upper side of the pushing clamp plate, so that the output end of the thruster can always reach the extension block during the change of the position of the pushing clamp plate.

[0008] Preferably, a long rod extends and is hinged to the rear side of the thruster, and a sleeve block is installed at the independent end of the long rod, which is locked to one side of the adjustment plate.

[0009] Preferably, the adjustment plate has multiple holes spaced horizontally at intervals, which allow the sleeve block to be inserted and secured.

[0010] Preferably, the thruster can be a vacuum extrusion thruster or a hydraulic thruster. Beneficial effects

[0011] After adopting the above technical solution, this utility model has the following advantages compared with the prior art: This utility model is a dual-purpose hydraulic clamp for turnouts. Combining the characteristics of turnout equipment, a hydraulic clamp that conforms to the characteristics of track operation is designed. The specific design of the connection structure allows the thruster to be applied to the pre-clamping body component to replace manual force to pry open the crowbar. The entire process of removing the eccentric sleeve is realized by the thruster. It can not only realize the flexible assembly of each component of the hydraulic clamp, but also effectively stabilize the relative position of the thruster and the clamping body component, avoiding positional displacement during the thrusting process. Ultimately, the whole process is time-saving and labor-saving, thereby improving work efficiency, reducing work risks, reducing maintenance costs, reducing work safety risks, and reducing the damage rate of the turnout eccentric sleeve.

[0014] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0015] like Figure 2 As shown: A turnout dual-purpose hydraulic clamp includes a thruster 6 and a clamp body component. The clamp body component includes a clamping clamp plate 7 for hooking and positioning on the gauge block 5. The clamping clamp plate 7 is hinged to a pushing clamp plate 8 at an adjacent position by means of an adjusting plate 9. After the pushing clamp plate 8 is adjusted at an angle relative to the adjusting plate 9, it hooks to the rear side of the eccentric sleeve 4 to achieve positioning and engagement of the eccentric sleeve 4.

[0016] The thruster 6 can be a vacuum extrusion thruster 6 or a hydraulic thruster 6.

[0017] See appendix Figure 2-4As shown, corresponding connecting structures are provided on the thruster 6 and the clamping body component to enable flexible assembly and application, and to effectively stabilize the relative position of the thruster 6 and the clamping body component, avoiding positional displacement during the thrusting process.

[0018] The connecting structure includes a sleeve seat 11 and a clamp 12 mounted on the upper side of the clamping jaw plate 7. The sleeve seat 11 is fixed to the upper side of the clamping jaw plate 7, and a screw 15 is welded to the lower end of the clamp 12. The screw 15 can be threaded to the sleeve seat 11 for fixation. The clamp 12 can clamp and limit the front position (cylindrical) of the thruster 6. Secondly, an extension block 10 is provided on the upper side of the pushing jaw plate, so that the output end of the thruster 6 can always reach the extension block during the change of position of the pushing jaw plate 8.

[0019] As a further restriction on the position of the thruster 6, a long rod 14 is extended and hinged to the rear side (the lower side when in use) of the thruster 6. A sleeve block 13 is installed at the independent end of the long rod 14. The sleeve block 13 can be locked with the adjustment plate 9, so that the rear side of the thruster 6 and the front side form an effective support and fastening, thereby safely applying force to the clamping body component.

[0020] Specifically, multiple holes are horizontally spaced on the adjustment plate 9, which allow the sleeve block 13 to be inserted to achieve pre-adjustment and positioning.

[0021] It should be noted that during assembly, the sleeve block 13 should be pre-clamped to the position of the adjusting plate 9 before fixing the front side of the thruster 6 to the clamp 12.

[0022] The above-described embodiments are provided for illustrative purposes. Based on the above description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this utility model is not limited to the contents of the specification; its protection scope must be determined according to the claims.
